Murai includes the so-called pericope adulterae, John 7:53-8:11, in his outline. This is a disputed passage that almost certainly was not part of John’s original manuscript. However, I think that the chiastic parallels are actually stronger if this passage is omitted. Murai suggests that 7:53-8:11 parallels 10:1-21, and links the Pharisees’ lack of understanding. I suggest the following arrangement, starting with Murai’s pairing of living water with the raising of Lazarus:

7:37-39 Living water7:40-44 Division and seeking to arrest7:45-52 The shepherds of Israel8:12-30 Light of the world8:31-59I AM9:1-41 A man born blind healed; the blindness of the Pharisees10:1-18 The great shepherd10:19-39 Division and seeking to arrest10:40-11:54 Crossing the Jordan and the healing of Lazarus

This serves as a small and secondary confirmation the disputed passage is not original to John.

The fact that the center of John involves a discussion of light and seeing and what is “above” is also striking, especially following a discussion of water. This suggests to me that Murai’s overall chiasm could be bracketed into seven sections that track the days of creation (central day four being the heavenly lights, following day three’s separation of land and waters).
